TRANSCRIPT
Ref. 710Screen-Printed Prussian Blue/Carbon Electrode
Disposable Screen-Printed Prussian Blue/Carbon Electrodes (ref. 710) are ideal for the determination of
hydrogen peroxide at a low detection potential. These electrodes are recommended for the development of
enzymatic biosensors based on oxidases, for working with microvolumes and for decentralized assays.
Ceramic substrate: L33 x W10 x H0.5 mm
Electric contacts: Silver
The electrochemical cell consists on:
Working electrode: Prussian Blue/Carbon (4 mm diameter)
Auxiliary electrode: Carbon
Reference electrode: Silver
Screen-printed Prussian Blue/Carbon Electrodes are commercialised in 75 units packs. They should be
stored at room temperature, protected from light in a dry place.
